I wish it had multiple choice though. Other than that love it. - **2★ · Just ok · August 28, 2017** — This is not nearly as detailed as I hoped it would be. It gives only a brief description of the 12 leads, and doesn't delve into the meaning of them. For example, one shows LVH with "strain pattern," but doesn't tell you what LVH is, how to detect it, and what it means. Nor does it do so with the strain pattern. There are no quiz questions beyond simply showing you 12 leads. Very frustrating! This app is overpriced for what it is. It should be .99. - **4★ · A bug and a little more · September 11, 2011** — First I want to say it is a good app. Great ECG's that will give you a great study tool. The only thing that slows me down right now with it is when I zoom in to take a closer look at the ECG's the images are extremely touchy. What I mean is when I try and move the ECG around with my finger, after about 10 seconds of it being zoomed in, the ECG's will jump from one end of the ECG to the other when I try and only move it from lead 1-3 over to maybe V1-V3. And sometimes it moves it completely off the screen and I have to try and find it or give up and zoom out. But the ECG images themselves are great quality and a great challenge. Second the app could be even better if there was maybe a study section that showed examples and explanations of the STEMI mimics. I'm sure the app is large enough but a small section that gave a better explanation of what benign early re-polarization looks like would in my mind makes this app the ultimate 12 lead study app. Great work!!! ## About Master 12-Lead ECG Interpretation with Confidence Sharpen your ECG interpretation skills with 12-Lead ECG Challenge—the ultimate tool for EMS providers, nurses, and physicians.
